1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The human microbiome comprises an ample set of organisms that inhabit and interact within the human body, contributing both positively and negatively to our health. In recent years, several research groups have described the presence of microorganisms in organs or tissues traditionally considered as 'sterile' under healthy and pathological conditions. In this sense, microorganisms have been detected in several types of cancer, including those in 'sterile' organs. But how can the presence of microorganisms be detected? In most studies, 16S and internal transcribed spacer (ITS) ribosomal DNA (rDNA) sequencing has led to the identification of prokaryotes and fungi. However, a major limitation of this technique is that it cannot distinguish between living and dead organisms. RNA-based methods have been proposed to overcome this limitation, as the shorter half-life of the RNA would identify only the transcriptionally active microorganisms, although perhaps not all the viable ones. In this sense, metaproteomic techniques or the search for molecular metabolic signatures could be interesting alternatives for the identification of living microorganisms. In summary, new technological advances are challenging the notion of 'sterile' organs in our body. However, to date, evidence for a structured living microbiome in most of these organs is scarce or non-existent. The implementation of new technological approaches will be necessary to fully understand the importance of the microbiome in these organs, which could pave the way for the development of a wide range of new therapeutic strategies.
